IROBERT G. CARGILL, OF MINNErkPOLIS, MINNESOTA, ASSIGNOR TO STANDARD BAKING- COMPANY, OF MINNEAPOLIS, -1VIINNESOTA, A CORPORATION OF MINNESOTA;

MACHINE FOR BAKING ICE-CREAM CONES.

Application filed June 28, 1913.

To all'whom it m concern Be it known that 1. Roman" G. .CARGILL, a

"citizen of "the United States, residing at for Baking Ice-Cream Cones: and I do hereby declare the following to be a full, clear, and'exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the This'iii-vent-ion has for its object to pro- :videan' improved machine for baking ice vcream cones and similar articles, and to such ends, generally stated,- the invention consists of the novel devices and combinations of devices hereinafter described and defined in the claims.

The invention is illustrated in the accompanying drawings wherein like characters indicate like parts throughout the several views.

Referringto the drawings, Figure l is a view in front elevation showing the improved machine, some parts being sectioned; Fig. 2 is a side elevation of the improved machine; Fig. 3is a detail taken in section approximately on the irregular line m m on Fig. 4; Fig. 4 is a view partly in side elevation and partly in vertical section on the line :0 r on Fig. l; and Fig. 5 is a horizontal section taken approximately on the line m on Fig. 4, some parts being broken away.

The relatively fixed framework of the machine, as shown, comprises abase platel having rigidly secured end bearingsQ and intermediate cam plates 3. The said plate 1 .is provided with rigidly secured laterally projecting horizontal bars 4 that are adapted'to be bolted, or otherwise rigidly secured to a bench or table. Upright and parallel guide columns 5 are rigidly seated 'in and project upward from,the end bearings}. A heavy rocking bar 6 is provided with trunnions at its ends journaled in the fixed bearing 2, and the hollow outer cones 7, of which there may be any desired number, are provided at their lower ends with trunnions that are suitably seated in the said rocker bar 6, and are provided at their lower ends with radially projecting arnis 8. Said arms 8 are connected to a common tie bar 9, so

that all of the several outer cones 7 Will 're- Specification of Letters Patent.

ceive simultaneous oscillatory movements.

The tie bar 9 is provided with a projection 10 that serves as a hand piece or lever for simultaneously oscillating all of the said outer cones 7, for a purpose which will presently appear.

The end bearings 2 are provided with forwardly projecting arms 11' in which a rock shaft 12 is journaled. This rock shaft 12,

at its ends, is provided with arms 13, one of which has an extension 14 that serves as an operating lever.

The inner cones 15 are secured to a commonoscillatory horizontal supporting bar 16, which, at its ends, is provided with sleeve-like bearings 17 that slide vertically on. the guide columns Links 18 connect the arms 13 to the said bearing 17, and so that by oscillatory movements of the operating lever 14. the said inner cones 15 may be simultaneously raised and simultaneously lowered at will. To the extreme upper ends of the inner cones 15 are secured disk- 'like heads 19 that have circiunferentially spaced conical pointed pins 20, engageable with the upper outer edges of the outer cones .7 to insure accurate centering of the cotiperating inner and outer cones, when the latter are moved downward into the former. Theouter cones 7 are tormed with internal circumferentially spaced longitudinally extended ribs 21 which will produce slight cor rugations or grooves in the outer surfa oes of the baked cones.

The rocker bar 6 is provided with aradially projecting operating lever 2-2, by means of which it may be oscillated to move the outer cones 7 from their vertical positions shown in Figs. 1 and 4, into or slightly below the position shown in Fig. 2.

Working through the lower ends of the outer cones 7 are ejecting plungers 23, which, at their lower or outer ends, are provided with roller-equipped studs 24, that work in cam grooves of the cam plates 3.

The cam grooves 25' are eccentric to the axis into approximately horizontal positions, the

ejecting plungers, by the actionof the lower equipped studs. 24:, and cooperating cam.

grooves 25, will move the saidejectingplungel-s inward and thus force the baked cones from the respective outer cones 7 Obviously, movements of the outer cones 7 from their horizontal, back into their vertical positions, will cause downward ret'ractions of These pipes 26 are, as shown, connected byshort valve-equipped'pipes 27 to a gas'supply pipe 28 that is connected-to a suitable source of gas supply. The said pipe 28,. as shown, issupported by short metal bars'29 rigidly secured to the rocker bar 6. For heating the inner cones-15, they are, as shown, provided with axial conduits 30 and oblique discharge conduits 3 Tubes '32 are screwed into the upper en s of the said inner cones 15 and commingled with the axial conduits- 30 thereof. At their upper ends, the tubes 32 are provided with valveequipped nipples 33 andi34c to which air and gas supply pipes, tobe attached. When the air and gas supply pipes 33 and 34 are opened, a m xture of air and gas will be delivered into and may be burned within the inner cones 15. 'The'tube 32 is provided with-a lateral opening 35 and with a valve, in theform of a sliding collar 36, foropening and closing said port 35. When the port 35 is opened, the coininingled air and gas may be ignited by inserting a burning match into the said port.

(lperationt 'lhe operation is substantially as follows: The dough will be inserted into the hollow outer" cones 7 while they are in upright positions shown in Figs. 1 and 4,

and while the inner cones 15 are raised, as

shown in Fig. 2. After the dough has been inserted, the inner cones 15 are lowered into the outer cones, by an upward oscillatory movement of the o crating lever 14. After,

the cones have bee baked, the lever 14: is slightly depressed so as to slightly raise the inner cones'15, and under this operatiomthe bakedcones, which will adhereto the inner cones, will be slightly raised within the outer cones. The said inner cones, with the.

baked cones adhering thereto, are immediately again lowered into the outer cones,-

and then by manipulation of the lever 10, the outer cones 7 are given a simultaneous oscillatory movement. lVhen the outer cones are thus oscillated, the ribs 21 thereof will cause the halted cones to o cillate thererespectively, are adapted;

with, and hence, to loosen themselves from the nner cones 1 5, This being done, the inner cones 15 are again raised by manipu .lation of the lever 14:. Next, the outer cones 7 with the bakedcones' loosely held therein, are, by manipulation of the-lever22, turned into the position shown. in Fig. 2, or to a.

movement'as already indicated in a general way, the e]ect1ng plungers 23, by cooperation of the roller-equipped notches 24c and operations above described be repeated.

This machin while 'ofsimple construction, has, in practice, been found highly e cient for the 'purposes'had in view. In the drawings,"only three cones 7 and three cooperating cones 15 are shown, but in practice, a very much larger number would be employed. o I v While the machine is especially adapt-ed to bake what is known as ice cream cones,

it is obvious that by the proper modification in the form of'the inner and outer cones, of the cooperating mold members, articles of various other design may be formed.

What I claim is:

1. In a machine for making ice cream cones and-the like, the combination with a plurality of outer mold members mounted for rotary movements on their own axes and for common oscillatory movement to and from upright positions, ofmooperating inner mold members mounted for vertica movements to and from said outer mold members. i
